Recommendations about Genera Competing for Use in the Leotiomycetes

P. Johnston, K. Seifert, J. Stone, A. Rossman, L. Marvanova

Abstract:

In moving to one scientific names from fungi resulting from changes to Article 59 introduced

with the Melbourne Code, this paper treats genera competing for use in the phylogenetically

defined class Leotiomycetes except for genera of the Erysiphales. Two groups traditionally

included in the so-called “inoperculate discomycetes” have been excluded from this class and

are also not included here, specifically the Geoglossomycetes and the Orbiliomycetes. A

recommendation is made about the generic name to use in cases in which two or more

generic names are synonyms or taxonomically congruent along with the rationale for the

recommendation. In some cases the recommended generic name does not have priority or is

based on an asexual type species and thus needs approval according to Art. 57.2 of the

International Code of Nomenclature of algae, fungi and plants (ICN). A table is presented

listing all competing generic names and their type species noting the recommended generic

name. The following new names are introduced:

Key words: Ascomycetes, Fungi, inoperculate discomycetes, one name-one fungus, unit

nomenclature

Introduction

As a contribution to the ‘one fungus-one name’ process resulting from changes to Article 59

introduced with the Melbourne Code (McNeill et al. 2012), this paper treats genera

competing for use in the class Leotiomycetes. A recommendation is made about the generic

name to use in cases where two or more generic names are synonyms or taxonomically

congruent. In some cases the recommended generic name does not have priority or is based

on an asexual type species and thus needs approval according to Art. 57.2 of the International

Code of Nomenclature of algae, fungi and plants (ICN). The background to the changes in

the Code and the need for papers such as this to assist in the development of lists of accepted

names (McNeill et al. 2013, Article 14.13) is provided by Rossman et al. (2013).

Many species of the Leotiomycetes have cup-shaped, often stalked ascomata with a widely

exposed hymenium of unitunicate asci and sterile paraphyses arranged in a compact palisade.

These fungi are ecologically diverse and include plant pathogens, saprobes of leaves and

wood, endophytes, mycorrhizas, and aquatic hyphomycetes (Wang et al. 2006a,b). This

breadth of ecology means that different research communities have worked more or less

independently on these fungi, for example, some primarily dealing with asexual taxa while

others primarily with sexual taxa or some working on plant pathogens and others on aquatic

fungi. In an attempt to determine the correct single name to be applied to a pair of sexual-

asexual genera, these communities are working together to determine the “best” or most

widely accepted name for those genera that represent the same group of related species

regardless of whether the type species represents the sexual or asexual state.

Traditionally the Leotiomycetes having morphologically similar ascomata and asci were

regarded as an informal group termed the “inoperculate discomycetes” as opposed to the

“operculate discomycetes” or Pezizales. However, the phylogenetically defined class

Leotiomycetes within the subphylum Pezizomycotina does not include groups previously

considered to be “inoperculate discomycetes such as the Orbiliomycetes and

Geoglossomycetes (Wang 2006 a,b; Husted & Miller 2011); these groups are not considered

in this paper. The class Leotiomycetes includes the ecologically specialised Erysiphales, the

powdery mildews (Braun & Cook 2011); however, the genera of this order are not dealt with

in this paper.

Within the Leotiomycetes, considerable taxonomic confusion exists at all levels, thus the

orders and families are not mentioned for the genera considered here.The confusion extends

to the genus level, making decisions about connections between many of the genera based on

sexual and asexual states impossible at this time. For example a confused taxonomy has

existed for the genera Mollisia and Cadophora. After de Hoog et al. (2000) showed that the

type species of Phialophora is not a member of the Leotiomycetes, the name Cadophora

Lagerb. & Melin was adopted by Gams (2000) for the phialophora-like asexual states of

some Mollisia spp. Subsequently, it was determined that specimens representing the type

species of Mollisia, M. cinerea, and Cadophora, C. fastigiata, belong in divergent clades

(Day et al. 2012, Baschien et al. 2013) and these two genera do not represent the same

lineage. A maximum likelihood tree places Cadophora sensu stricto into Rhynchosporium

(Baschien et al. 2013) along with Mollisia dextrinospora, whereas Mollisia sensu stricto

3

belongs in the Vibrissea-Loramyces clade (Wang et al. 2006a,b). Thus these genera are not

taxonomically congruent, meaning that they do not circumscribe the same set of species and

thus do not compete with each other for use as the single name for the genus represented by

the type and related species.

Taxonomic confusion also results if a genus as currently conceived is not monophyletic. For

example, the type species of the large genus Lophodermium is the grass-inhabiting L.

arundinaceum (Johnston 2001). This species is phylogenetically distinct from the important

pine-inhabiting species such as Lophodermium pinastri and L. seditiosum (Lantz et al. 2011).

In determining which genus names might compete with Lophodermium, only the type species

influences this decision. The pine-inhabiting species must be placed in another genus unless

Lophodermium is conserved with a new type species from among the pine-inhabiting species.

The names of the asexual states connected with species of Lophodermium on pine such as L.

conigenum are placed in Leptostroma in this case Leptostroma pinorum (Minter 1980).

However, the type species of Leptostroma is L. scirpi, again not congeneric with L. pinorum

(Lantz et al. 2011). Thus, although Lophodermium conigenum is the sexual state of

Leptostroma pinorum, neither genus is appropriate for these species. Thus, in establishing the

correct names for competing genera, the first step is always to review the phylogenetic status

of their type species.

Many of the generic names of Leotiomycetes are old, especially those of the asexual states.

DNA sequences are available for few of the type species, most certainly not from the type

specimen but also not from any representative or epitype specimen. Thus, resolving the

taxonomic issues amongst these fungi is at present difficult. Knowing the phylogenetic

position of the type species of competing genera is crucial. In addition, many genera,

especially those applied to asexual states, are polyphyletic often including several hundred

names described in the 1800’s that have since been placed outside the genus or that remain

obscure. This has resulted from asexual genera having previously been regarded as form-

genera rather than representing monophyletic genera.

In reviewing the potential competing generic names for sexual and asexual states of aquatic

fungi, it was determined that none of these appear to be truly taxonomically congruent. The

few connections between sexual and asexual states are the result of polyphyletically defined

genera in which the type species is not congeneric with the names used for the linked species

4

names, e.g., for the monotypic genus Dimorphospora, sexual state Hymenoscyphus was described.

The type species Hymenoscyphus fructigenus and Dimorphospora foliicola are very probably not

congeneric . BLAST search does not link Dimorphospora with Hymenoscyphus, and also in Baschien

et al. (2013) the ex-type culture of Dimorphospora foliicola does not appear in a clade together with

Hymenoscyphus. Tricladium splendens, type of the genus Tricladium with the sexual state

Hymenoscyphus splendens, appears closely related to Hymenoscyphus varicosporoides

(Seena et al. 2010, Baschien et al. 2013), but H. varicosporoides is referred to in Sivichai et

al. (2003) as sexual state of a Tricladium considered conspecific with T. indicum isolate from

South Africa, for which Webster et al. (1995) described the sexual state Cudoniella indica.

Given the extreme differences in morphology between the aquatic hyphomycetes and their

sexual states, determining whether these taxa are congeneric is difficult without molecular

phylogenetic data.

This paper is based on the current state of knowledge for each set of generic names that are

determined to be synonyms or taxonomically congruent as defined below. Genera of sexual

and asexual morphs that are known to circumscribe the same group of species were

investigated. The generic names compete for priority regardless of whether the type species

represent a sexual and asexual morph. Current literature was investigated to determine

whether the sexual and asexual genus names based on their respective type species are truly

congeneric. Data about the phylogenetic placement of each genus are considered. If the type

species of both the sexual and asexual genera are considered to be taxonomic synonyms, then

the respective genera are described as synonyms. If the type species of one genus is judged to

be congeneric with the type species of the other genus based on current knowledge, i.e. the

type species are regarded as circumscribing the same set of related species, these generic

names are described as taxonomically congruent.

Based on the literature and discussion among users, one genus of the pair is recommended for

use. By default, following the Code, the generic name that has priority, i.e. the name that was

described first, is recommended. However, our choice is based on a number of factors and

sometimes recommends that priority be over-ruled. One factor is the potential number of

names changes required as included partially by the number of species names placed in each

genus. This was determined by consulting current literature and by the number of names

listed under each genus in Index Fungorum. A second factor is the frequency of use of each

genus name as determined by searches of database resources such as Google, Google

5

Scholar, MycoBank, and SMML Fungal Databases. Consideration was given to which genus

name was used most commonly and of its importance to user communities. Finally this

document was circulated among a number of users as indicated in the Acknowledgements.

Pairs of genera are presented in Table 1 with the recommended genus listed first and in bold.

This is followed by a discussion for each genus of the rationale for this recommendation. In

the discussion the following terms are used. If a sexual genus that is younger than an asexual

genus is recommended for use, then the term conserve is used indicating that this genus does

not have priority and thus must be effectively conserved. If an asexual genus has priority i.e.

it is the oldest genus, and is recommended for use, then the term protect is used indicating

that this genus has priority but has an asexual type species and therefore must be protected as

dictated in Article 57.2 of the ICN. These are the two situations in which action is needed

such that these genera must be approved by the Committee for the Nomenclature of Fungi of

the IBCN. In addition for competing genera in which the genus representing the sexual state

has priority and is recommended for use, not action is needed. In Table 1, the recommended

generic name is listed first and in bold. For each generic name, the place of publication and

the type species with its place of publication and the currently accepted species name are

listed. Additional synonymous generic names are listed in the third column. If action is

needed, this is noted in the last column. In cases in which an older epithet exists for the type

species of a genus recommended for use, or a few new combinations are needed, these new

combination are made in this paper.

Rationale for recommendation of single generic name:

Protect Ascoconidium 1942 over Sageria 1975

The type species Ascoconidium, A. castaneae, was described as the asexual state of Dermatea

purpurescens (Seaver, 1942) while the type species of Sageria, S. tsugae, is the sexual state

of A. tsugae (Funk 1975). Although one might question whether these two species are

congeneric, Nag Raj & Kendrick (1975) present a convincing case for this in that both

asexual states have large phialides that rupture at the apex with conidiogenous cells at the

base of the phialide and large, cylindrical, multiseptate conidia. The sexual states are likewise

similar. Thus these generic names are regarded as synonyms. These two genera each with two

names are both well characterised. Neither genus is particularly widely used, thus, the older

asexual genus is recommended for use. The most commonly reported species is Sageria

purpurescens (≡ Dermatea purpurescens) occurring on Castanea in eastern North America

6

(Verkley 1999). One argument for Sageria would be that the word ‘ascoconidium’ is also

used as a technical term. If Ascoconidium is used and S. purpurascens is considered a

synonym of the type species, A. castaneae, then the basionym Dermatea purpurascens must

be transferred to Ascoconidium.

Conserve Ascocalyx 1926 over Bothrodiscus 1907 and Pycnocalyx 1916.

The sexual genus Ascocalyx, type species A. abietis, and the asexual genus Bothrodiscus,

having the type species B. bernice now referred to as B. pinicola, were shown to be the sexual

and asexual morphs of the same species by Groves (1936). In addition the monotypic genus

Pycnocalyx, type species P. abietis, is also a synonym of A. abietis. Thus, these three generic

names are considered synonyms. Seven names have been placed in Ascocalyx with only four

remaining in that genus, while two of the three names in Bothrodiscus are synonyms. All

species of this genus occur on the Pinaceae. Ascocalyx is the most commonly used genus,

therefore, we recommend that Ascocalyx be conserved. This requires that the scientific name

of the type and most commonly encountered species, a fungus causing a canker on pine

(Kondo & Kobayashi 1984), would need to be changed.

Conserve Ascodichaena 1977 over Polymorphum 1822.

Butin (1977) established Ascodichaena based on the type species A. rugosa as a sexual name

for the asexual Polymorphum rugosum, thus these two generic names are synonyms. The type

species of Polymorphum, P. faginea, was validated by Hawksworth & Punithalingham (1973)

7

because the basionym Opegrapha faginea was invalid. All species of Polymorphum are

considered synonyms of P. rugosum, now A. rugosum. A second species of Ascodichaena, A.

mexicana, was described by Butin (1990). Ascodichaena is used more frequently than

Polymorphum, thus Ascodichaena is proposed for conservation.

Conserve Blumeriella 1961 over Microgloeum 1922 and Phloeosporella 1924 and

conserve the name B. jaapiii.

Blumeriella jaapii, the type species of Blumeriella, causes shot-hole of Prunus, a common

disease in temperate regions. The asexual morphs of this species have been referred to as

Phloeosporella padi for the macroconidial state and Microgloeum pruni for the microconidial

state. Because M. pruni is the type species of Microgloeum, the generic names Blumeriella

and Microgloeum are synonyms. The name P. padi based on Ascochyti padi Lib. 1832 and

also commonly used for cause of shot-hole of Prunus is not the type species of Phloesporella.

At present it is unclear if Phloeosporella is congeneric with Blumeriella and Microgloeum as

no molecular sequence data exist for the type species of Phloeosporella, P. ceanothi, causing

leaf spot and dieback of Ceanothus. Given the common use of the name Blumeriella jaapii

for the cosmopolitan shot-hole disease of Prunus, it seems useful to conserve the generic

name Blumeriella over Microgloeum and Phloeosporella. In addition, the species name,

Pseudopeziza jaapii would need to be conserved over the older names Ascochyta padi 1832

and Hainesii fuerichii 1906. Given the prevalent use of Blumeriella jaapii for this disease and

the lack of certainty about its relationship to the type species of Phloeosporella, it seems

prudent to conserve the genus Blumeriella and the species name for B. jaapii.

Protect Botrytis 1794 over Botryotinia 1945.

Botrytis cinerea, the type species of Botrytis, is an important and ubiquitous plant pathogen.

When the sexual morph of Botrytis cinerea was discovered, it was placed in the genus

Botryotinia as B. fuckeliana (Whetzel 1945). The type species of Botryotinia, B. convoluta,

basionym Sclerotinia convoluta and Botrytis cinerea are undoubtedly congeneric as indicated

using ITS sequences (Holst-Jensen et al. 2004), thus Botrytis and Botryotinia are

taxonomically congruent. At present 414 names of taxa have been included in Botrytis while

there are only 20 names in Botryotinia, most of which already have names in Botrytis. Given

the frequency with which Botrytis cinerea is observed, recognition of this name, and the

8

number of described species in Botrytis, it seems expedient to propose the generic name

Botrytis for protection over Botryotinia. This reflects the unanimous vote for Botrytis, taken

following a round-table discussion amongst the approximately 100 delegates at the 16th

International Botrytis Symposium, 23-28 June 2013, Locorotondo, Italy.

Use Calloria 1836 rather than Cylindrocolla 1851, Creothyrium 1925 or Callorina 1971.

The type species of Calloria, C. fusarioides, more recently regarded as C. neglecta, is

considered the sexual state of the type species of Cylindrocolla, C. urticae, thus these two

genera are synonyms (Hein 1976, Seifert 2011). Callorina was also described for this same

species, another synonymous generic name. The monotypic genus Creothyrium based on C.

pulchella is obscure but Sutton (1977) considered it to be a synonym of Cylindrocolla.

Calloria includes 122 names only a few of which have been accounted for in recent

monographs such as Hein (1976) while Cylindrocolla includes 33 names most of which have

never been considered in recent literature. No molecular data exist for any species of this

genus. Calloria has priority and is the more commonly used genus, thus that name should

continue to be used. However, the oldest epithet for the type species of both Calloria and

Cylindrocolla must be transferred to Calloria.

Protect Chaetomella 1870 over Zoellneria 1934, Volutellospora 1965 and Harikrishnaella

1972.

9

Recent research has demonstrated that Chaetomella based on the type species, C. oblonga, is

congeneric with Zoellneria based on Z. rosarum (Johnston & Baral pers. comm.). Many more

species have been included in Chaetomella and are widely reported from plant hosts

(Rossman et al. 2004) while Zoellneria is a relatively obscure genus. Volutellospora and

Harikrishnaella were shown to be synonyms of Chaetomella (Rossman et al. 2004). Given

the frequent citation of Chaetomella and the number of species included in that genus, it is

recommended to follow the principle of priority and protect Chaetomella to use for this

genus.

Conserve Chlorociboria 1958 over Dothiorina 1911

The type species of Chlorociboria is the commonly encountered C. aeruginosa and the genus

includes 34 names, although these represent many fewer species. The monograph of

Chlorociboria (Dixon 1975) suggested that the asexual morph of C. aeruginascens might be

Dothiorina based on D. tulasnei but the evidence is not convincing. This fungus was little

known until Sanchez & Bionchinotti (2007) provided a detailed description including

conidiogenesis. They did not consider that it was the asexual state of C. aeruginascens. They

also excluded or doubted that the two other species in Dothiorina belonged in that genus.

Thus it is unclear if these genera are synonyms, however, based on Dixon (1975) a

connection has been assumed. Given the widespread use of Chlorociboria and the number of

species included in that genus, Chlorociboria is proposed for conservation.

Conserve Claussenomyces 1923 over Dendrostilbella 1905.

The type species of Claussenomyces, C. jahnianus, was included in a monograph of this

genus by Korf & Abawi (1971) with a key to four species including C. prasinula (≡ Peziza

prasinula). Seifert (1985) presents a thorough account of the type species of Dendrostilbella,

D. prasinula, considering this to be the asexual state of Claussenomyces prasinula based on

Dennis (1956) and his observations. Seifert (1985) noted that the morphological species, D.

prasinula, was associated with both C. prasinula and C. atrovirens (Pers.) Korf & Abawi.

Based on these publications it appears that Claussenomyces and Dendrostilbella are

taxonomically congruent. Although 23 names were described in Dendrostilbella, many have

been placed in other genera. Nineteen species are currently accepted in Claussenomyces

based on Gamundi & Gialotti (1995), Korf & Abawi (1971), Medardi (2007), and Ouellet &

10

Korf (1979), although some of these species may not be congeneric with C. jahnianus.

Considering the amount of recent taxonomic work on Claussenomyces and the number of

accepted species, it seems advisable to conserve Claussenomyces for this genus.

Protect Coma 1972 over Ascocoma 1987.

The type species of Coma is congeneric with the type species of Ascocoma (Swart 1987,

Beilharz & Pascoe 2005), thus these genera are synonyms. Both names are relatively obscure

with about an equal number of reports. Using Ascocoma would require transferring

Pestalozziella circularis into that genus while use of Coma requires only that the orphan

variety, A. eucalypti var. didymospora, be transferred to Coma.

Protect Coryne 1816 over Pirobasidium 1902 and Ascocoryne 1967.

The genus Coryne based on C. dubia includes 69 names, few of which have been considered

in the last fifty years. The genus Ascocoryne based on A. sarcoides was described for the

sexual state of C. dubia, thus their connection is established and these two genera are

synonyms. The earlier monotypic genus Pirobasidium based on the same type species as

Ascocoryne was overlooked by Grove & Wilson (1967) when they described Ascocoryne.

Only seven names are included in Ascocoryne, suggesting that conserving Ascocoryne may

require numerous name changes although this could be questioned because most of the names

in Coryne are obscure. The concept of this genus based on Ascocoryne is well circumscribed

and a number of recent papers deal with non-taxonomic aspects of species as Ascocoryne.

Also, Coryne is used for a genus of hydrozooans. Considering the number of potential name

changes if Ascocoryne were used and the priority that Pirobasidium has over Ascocoryne, it

seems best to protect the generic name Coryne.

Protect Crinula 1821 over Holwaya 1889.

11

The type species of the genus Crinula, C. caliciiformis, was shown to be conspecific with the

type species of Holwaya, H. ophiobolus, now regarded as H. mucida, (Korf & Abawi 1971),

thus these generic names are synonyms. Neither name has been used more commonly than

the other. Ten names and two varieties have been included in Crinula although most of the

names are relatively unknown. Four names in Holwaya are synonyms of H. mucida and thus

would be regarded as C. caliciiformes. The two remaining names in Holwaya have been

placed outside the genus, thus no name changes are required if Crinula is protected.

Protect Cristulariella 1916 over Nervostroma 2006.

The genus Nervostroma based on N. depraedans was established for the sexual state of

Cristulariella depraedans, type of Cristulariella, thus these generic names are synonyms

(Narumi-Saito et al. 2006). In the same article three species previously described in

Cristulariella were removed to Hinomyces (Narumi-Saito et al. 2006) having a sexual state in

Grovesinia. Thus, Cristulariella now includes three species while Nervostroma includes only

two. Neither name is widely used. Given that Cristulariella is the earlier name, it is suggested

that this asexual name be protected although this may lead to confusion with the species now

placed in Hinomyces.

Conserve Crumenulopsis 1969 over Digitosporium 1953.

The generic name Crumenulopsis, type species C. pinicola based on Peziza pinicola, was

established to replace the name Crumenula Rehm 1888 non De Not. 1864. Van Vloten &

Gremmen (1953) described Digitosporium piniphilum for the asexual state of Crumenula

sororia, now referred to as Crumenulopsis sororia. Although no molecular data exist to

determine whether C. pinicola and C. sororia are synonyms, this appears likely. Thus, the

generic names Crumenulopsis and Digitosporium are most likely synonyms and at the least

taxonomically congruent. At present six taxa are named in Crumenulopsis including C.

pinicola and C. sororia, both causing dieback diseases of pine in Europe, and C.

atropurpurea, causing a disease of Japanese red pine in Georgia (Hanlin et al. 1992). Because

the older, monotypic genus Digitosporium has not been widely used, it seems advisable to

conserve the name Crumenulopsis.

Conserve Dematioscypha 1977 over Schizocephalum 1852 and Haplographium 1859.

12

The genus Dematioscypha based on D. dematiicola is clearly circumscribed to include five

related taxa (Svrcek 1977, Huhtinen 1987, Hosoya & Otani 1997). The older genus

Schizocephalum, based on S. atrofuscum, includes four species none of which have been

considered since before 1900. The relationship of S. atrofusca to D. dematiicola is difficult to

determine. Schizocephalum atrofusca was placed in Haplographium by Saccardo (1886) but

no one has dealt with it since then. Based on Hughes (1953, 1958), recent authors have

considered H. catenatum (= H. delicatum, type of Haplographium) to be the asexual state of

Dematioscypha dematiicola (Huhtinen 1987). Thus, it seems likely that Dematioscypha and

Haplographium are synonyms as well as possibly Schizocephalum. Although 39 names are

listed in Haplographium, most have not been considered recently and those that have are

placed in other genera. Wang (2010) provides a key to species of Haplographium listing

diverse sexual states including one basidiomycete (Tomentella), thus one should consider

haplographium to be a morphology rather than a monophyletic genus. We suggest that

Dematioscypha should be conserved over Schizocephalum and Haplographium.

Schizocephalum as well.

Conserve Dermea 1825 over Sphaeronaema 1815 vs. Foveostroma 1978.

Dermea based on D. cerasi is a well defined genus that includes a number of plant

pathogenic species (Abeln et al. 2000). Although over 200 names have been placed in

Sphaeronaema, almost nothing is known about the type species, S. cylindricum. Most of the

names in Sphaeronaema that have been considered in the modern literature are now placed in

other genera. Whether Dermea and Sphaeronaema are taxonomically congruent is not

known. The genus Foveostroma was based on F. drupacearum, considered to be the asexual

morph of D. cerasi (DiCosmo 1978); thus, Foveostroma and Dermea are synonyms. Dermea

includes 31 names, while eight names have been described in Foveostroma. Among these

three genera Dermea is the most well known and some species have been sequenced (Abeln

et al. 2000). Based on the unknown placement of the type species of Sphaeronaema, the less

frequent use of Foveostroma, and the accepted status of Dermea, it seems advisable to

conserve the name Dermea over Sphaeronaema and Foveostroma.

Conserve Diplocarpon 1906 over Entomosporium 1856, Marssonina 1906, and

Entomopeziza 1914.

13

The type species of Diplocarpon, D. rosae, has been linked to an asexual morph in

Marssonina, M. rosae, for the serious disease of roses called black spot (Sivanesan & Gibson

1975a). The type species of Entomosporium, E. mespili, is used for the asexual morph of a

cosmospolitan leaf and fruit spot disease of rose and other rosaceous plants to which the

sexual state name, Diplocarpon mespili ( = Diplocarpon maculatum), has been applied

(Sivanesan & Gibson 1975b). A third genus, Marssonina based on M. potentillae as M.

fragariae, has a sexual morph referred to as D. earlianum (Sivanesan & Gibson 1975c) and

thus also competes for synonymy with Diplocarpon. Although the conidia of these species

appear superficially different because of the long appendages on the conidia of E. mespili,

developmental similarities to the conidia of M. rosae and M. fragariae have been noted (Farr

1993, Sutton 1980) as well as the morphologically similar sexual states. In addition ITS

sequences indicate that all three type species may be congeneric (unpublished). Thus,

Diplocarpon, Entomosporium, and Marssonina are considered taxonomically congruent. An

obsure fourth genus, Entomopeziza based on E. souraeri (= Entomosporium mespili) is a

synonym of Entomosporium. The number of names in Entomosporium and Diplocarpon are

about equal while Diplocarpon is more frequently used. Over 100 names have been placed in

Marssonina, but this genus has not been well defined and many of these names represent

unrelated species. Diplocarpon is well known for the serious, widespread diseases of

rosaceous plants and is widely known in plant pathology literature. We recommend the

conservation of Diplocarpon.

Use Gelatinipulvinella 1995 rather than Aureohyphozyma 1995.

The type species of Gelatinipulvinella, G. astraeicola, and Aureohyphozyma, A. astraeicola,

were described as the sexual and asexual morphs of the same species (Hosoya 1995). These

genera compete equally for use. Given the past preference for sexual state names, it is

recommended that Gelatinipulvinella be used.

Conserve Gloeotinia 1954 over Endoconidium 1891.

The genus Gloeotinia, with the type species G. temulentum based on Phialea temulentum,

was established for the sexual state of the same species and name Endoconidium E.

temulentum, type species of that genus. Thus, Gloeotinia and Endoconidium are synonyms.

14

Although six species have been described in Endoconidium and only four species in

Gloeotinia, the blind seed diseases caused by these fungi are most commonly referred to as

Gloeotinia granigena and G. temulentum. Their distinction as two different species has only

recently been reported (Alderman 1998). If Endoconidium were used, the relatively well

known name G. granigena would have to be changed, thus it seems expedient to conserve the

name Gloeotinia.

Conserve Godronia 1846 over Sphaeronaema 1815 and Topospora 1836.

Godronia, based on the type species G. muehlenbeckii on Phragmites communis in Europe,

was monographed by Groves (1965) and includes a number of plant pathogenic species,

primarily on woody dicotyledonous hosts. Only one species, G. urceolata, has been

sequenced (de Gruyter et al. 2009); thus, the phylogenetic placement of this non-type species

in the Leotiomycetes is confirmed but the relatedness of the type species to this genus to the

other species in Godronia or asexual morphs is unknown. Although over 200 names have

been placed in Sphaeronaema, almost nothing is known about the type species, S.

cylindricum based on Sphaeria cylindrica. This type species is relatively obscure and

undefined described on Quercus and Salix in Sweden and Germany. Most of the names in

Sphaeronaema that have been considered in the modern literature have been placed in other

genera. The taxonomic congruence of Godronia with Sphaeronaema is not known.

Topospora based on T. uberiformis is considered the asexual morph of Godronia uberiformis

on Ribes (Groves 1965, Sutton 1980), thus these genera are taxonomically congruent.

Godronia includes 88 names while eight species have been placed in Topospora. The type

species of several later asexual genera are linked to species placed in Godronia and these

generic names would be available for segregate genera. Based on the unknown phylogeny of

Sphaeronaema, the relative obscurity of Topospora, and the accepted use of Godronia, it

seems advisable to conserve the name Godronia.

Conserve Godroniopsis 1929 over Sphaeronaema 1815.

Godroniopsis is a small but well defined genus that includes two plant pathogenic species.

Over 200 names have been placed in Sphaeronaema, yet almost nothing is known about the

type species, S. cylindricum, as mentioned above. Most of the names in Sphaeronaema that

have been considered in the modern literature have been placed in other genera. It is not

15

known if Godroniopsis and Sphaeronaema are taxonomically congruent. Based on the

unknown phylogeny of Sphaeronaema and the accepted use of Godroniopsis, it seems

advisable to conserve the name Godroniopsis.

Conserve Gremmeniella 1969 over Brunchorstia 1891 and conserve the name G.

abietina.

The type species of Gremmeniella, G. abietina based on Crumenula abietina, has been used

for the sexual state of the same species as the asexual morph name Brunchorstia pinea based

on Septoria pinea, a synonym of B. destruens, the type species of the genus Brunchorstia. All

of these epithets are synonyms according to Punithalingam & Gibson (1973) Sutton (1980),

and Muller (1983) and, thus, there is no doubt that these two generic names are synonyms.

The disease caused by G. abietina is known as Scleroderris canker or Brunchorstia dieback of

pines. Although seven names have been placed in Gremmeniella, only four species are still

included in this genus. Among the seven names in Brunchorstia, only one remains in that

genus. The name Gremmeniella especially for G. abietina appears to be used more widely

than Brunchorstia, thus it seems expedient to conserve the name Gremmeniella.

Use Grovesinia 1983 rather than Hinomyces 2006.

The type species of Grovesinia, G. pyramidalis, is considered the sexual morph of the type

species of Hinomyces, H. moricola, thus these two genera are synonyms (Narumi-Saito et al.

2006). This fungus causes bull’s eye or zonate leaf spot on a number of hosts in the colder

regions of North America and Asia. Both genera have a second species, Grovesinia pruni (

Hinomyces pruni), that are also synonyms. The separation of species of Cristulariella into

different genera was first recognized by Narumi-Saito et al. (2006) as mentioned under

Cristulariella versus Nervostroma. Given that useage of Grovesinia and Hinomyces is about

equal, the oldest name, Grovesinia, is recommended for use. However, the oldest epithet for

this species must be transferred to Grovesinia.

Use Heterosphaeria 1824 rather than Heteropatella 1874.

The type species of Heterosphaeria, H. patella, is the sexual state of the type species of

Heteropatella, H. lacera (Leuchtmann 1987, Nag Raj 1993), thus these two genera are

synonyms. None of these species have been analyzed phylogenetically but Leuchtmann

(1987) provides a monographic account of the eight species accepted in Heterosphaeria. The

number of names in each genus is about equal and Heterosphaeria is slightly more

commonly used than Heteropatella. Because there is no compelling reason to do otherwise,

use of the oldest genera name, Heterosphaeria, is recommended.

Use Hypnotheca 1970 rather than Monochaetiellopsis 1977

The monotypic genus Hypnothecia based on H. graminis was described as the sexual morph

of the type species of Monochaetiellopsis themedae as its basionym Monochaetiella

themedae (Tommerup 1970), thus these genera are synonyms. Neither genus is especially

well known although several reports exist for the two species of Monochaetiellopsis (Nag Raj

1993). Given the obscurity of both genera, Hypnotheca has priority and thus is recommended

for use, however, this requires the transfer of the older epithet into Hypnotheca.

Conserve Hypohelion 1990 over Leptostroma 1815.

The type species of Hypohelion, H. scirpinum, is based on Hypoderma scirpinum which is

considered the sexual morph of Leptostroma scirpinum, the type species of Leptostroma. This

relationship was first established by Grove (1937) as Leptothyrium scirpinum ( Leptostroma

scirpinum) and accepted by Minter (1997) as Hypohelion scirpinum. Thus, Hypohelion and

Leptostroma are synonyms. The genus Leptostroma includes 208 names but many of these

have been removed to other genera. Although Sutton (1980) recognized Leptostroma, he only

17

included the type species. The remaining names in Leptostroma are of unknown phylogenetic

affinities; however, many species described in Leptostroma occur on Pinus (Minter 1980)

and are not congeneric with L. scirpinum (Lantz et al. 2011). One additional species has been

placed in Hypohelion, H. durum (Lin et al. 2004). Given the polyphyletic nature of the genus

Leptostroma now considered for species unlike the type, it would seem most useful to

conserve the well-characterized genus Hypohelion.

Use Micraspis 1963 rather than Periperidium 1963

The type species of Micraspis, M. acicicola, was described as the sexual morph of the type

species of Periperidium, P. acicicola, by Darker (1963), therefore, the genera are synonyms.

Two additional names have been placed in Micraspis and this name has been more frequently

used than the monotypic Periperidium, thus the use of Micraspis is recommended.

Protect Mycopappus 1985 over Redheadia 2005.

The type species of Mycopappus, M. alni, does not have a known sexual state; however, a

second species, M. quercus, is the asexual state of the type species of Redheadia, R. quercus

(Suto & Suyama 2005). When Redhead & White (1985) described M. alni, they suggestesd

that it was a sclerotiniaceous fungus as is M. quercus based on the apothecial sexual state

arising from a sclerotium. Thus, it seems likely that M. alni and M. quercus are congeneric

and thus the names Mycopappus and Redheadia are taxonomically congruent. Of the four

names in Mycopappus, the two other species in Mycopappus are placed in the

Dothideomycetes: M. aceris in Xenostigmina (Crous et al. 2009) and M. aesculi as the

asexual state of Mycodidymella aesculi (Wei et al. 1998). Mycopappus is a widely used

generic name but some of those references are to the species that no longer belong in that

genus. Nevertheless, it seems advisable to use the earliest name, Mycopappus, for this genus.

Conserve Neofabraea 1913 over Phlyctema 1847.

The genus Neofabraea is characterized by the type species N. malicorticis (Verkley 1999),

while the type species of Phlyctema, P. vagabunda is the asexual morph of N. alba (E.J.

18

Guthrie) Verkley 1999, thus Neofabraea and Phlyctema are congeneric. Following the

monograph of Verkley (1999), the genus Neofabraea is well understood and clearly

circumscribed. In contrast, more than 60 names have been placed in Phlyctema, some of

which have been transferred to genera such as Phomopsis and Rhabdospora, but the other

species of Phlyctema are spread among other genera of morphologically simple coelomycetes

(Verkley 1999). The virtually unknown genus Allantozythia is also a synonym of

Neofabraea. Given that Neofabraea has been monographed, is well characterized

phylogenetically (Abeln et al. 2000), and includes a number of plant pathogens that are

known in that genus, it seems expedient to conserve the name Neofabraea for this genus.

Use Oculimacula 2003 instead of Helgardia 2003.

These genera were described in the same paper based on the same species and thus are

synonyms having equal priority. Oculimacula includes two species while four species have

been placed in Helgardia. The name Oculimacula is used much more widely than Helgardia

by plant pathologists and others for the eyespot diseases of wheat and barley. Crous et al.

(2003) determined that the name commonly used for eyespot of wheat, Tapesia yallundae,

must be removed to another genus because the genus name Tapesia, based on T. fusca, is

now a rejected name (Hawksworth & David 1989). If the sexual morph genus Oculimacula

were used, the name for the eyespot disease of wheat would become O. herpotrichoides while

the name for the fungus causing eyespot disease of barley would remain O. acuformis. The

two remaining species in Helgardia should be transferred to Oculimacula.

New combinations needed or conserve T. yallundae!

Use Ovulinia 1940 rather than Ovulitis 1970.

The type species of Ovulinia, O. azaleae, is the sexual morph of Ovulitis azaleae, type

species of Ovulitis, thus these generic names are synonyms. Both genera include a second

species that are also synonyms. Because Ovulinia has priority, this name should be used.

Use Pezicula 1865 over Cryptosporiopsis 1912 and Lagynodella 1922.

The type species of Pezicula, P. carpinea, has an asexual state regarded as Cryptosporiopsis

fasciculata while the type species of Cryptosporiopsis, C. nigra, is the asexual morph of

Pezicula ocellata (Pers. : Fr.) Seaver (Verkley 1999). The genus Lagynodella based on L.

pruinosa as Cryptosporiopsis pruinosa is also a synonym of Pezicula. Both the monographic

account by Verkley (1999) and a phylogeny of these species (Abeln et al. 2000) suggest that

these three genera are taxonomically congruent. Pezicula and Cryptosporiopsis have similar

levels of use. Some species of Cryptosporiopsis has also been linked to Neofabraea and may

need to be placed in that genus while others have no known sexual morph. Verkley (1999)

notes that those species of Cryptosporiopsis linked to Neofabraea tend to have conidia less

regular in shape. Most species in common use already have names in Pezicula. Because a

monograph of Pezicula exists, this name should be used.

Protect the name Phacidiopycnis 1912 over Potebniamyces 1962.

The type species of Phacidiopycnis is P. malorum, now regarded as P. pyri (Windlmayr

1965). The genus Phacidiella Potebnia 1912 non P. Karst. 1884 was replaced by the name

Potebniamyces by Smerlis (1962) typified by P. discolor, now regarded as P. pyri.

Phacidiopycnis pyri is considered the asexual morph of Potebniamyces pyri (Brooks 1928,

20

Sutton 1980 as P. discolor), thus these two genus names are synonyms. Both Phacidiopycnis

and Potebniamyces are used in the plant pathology literature most recently in reference to a

canker and twig dieback of pear and also associated with pome fruits (Xiao and Boal 2005,

Xiao et al. 2005). A number of species also occur on conifers (Gross & Weidensaul 1967,

Punithalingam & Gibson 1976) but their phylogenetic affinites are not known. The frequency

of use and number of names is highest in Phacidiopycnis, therefore we recommend protecting

the asexual name Phacidiopycnis.

Use Phacidium 1815 rather than Ceuthospora 1826

The type species of Phacidium, P. lacerum, has an asexual morph named Ceuthospora

pinastri (DiCosmo et al. 1984.) while the type species of Ceuthospora, C. lauri, has been

linked to P. multivalve based on Sutton (1972) as C. phacidioides. The latter connection has

not been reviewed in the recently literature but, given the number of species of Ceuthospora

having sexual states in Phacidium, it seems likely that these genera are taxonomically

congruent. Issues concerning the type species of Ceuthospora and conservation of Greville’s

name were addressed by Sutton (1972). Ceuthospora lauri is known to cause a bleeding

brown zonate leaf blight of tea (Ando et al. 1989). The name Phacidium has been widely used

and includes a greater number of names than Ceuthospora, therefore we recommend use of

the older name Phacidium.

Protect Phialocephala 1961 over Phaeomollisia 2009.

Based on the phylogenetic study by Grunig et al. (2009), it is difficult to determine if the

monotypic genus Phaeomollisia is congeneric with Phialocephala. Although an isolate of the

type species of Phialocephala is included, it does not cluster strongly with Phaeomollisia.

Given that 35 names exist in the genus Phialocephala and the genus was recently

recircumscribed (Day et al. 2012), it seems expedient to use this older name. If they are not

congeneric, both genus names are available.

Protect Pilidium 1823 over Discohainesia 1932 and Sclerotiopsis 1882.

The type species of Pilidium, P. acerinum, was shown to be monophyletic with P. concavum,

which is considered to be one of the asexual morphs of Discohainesia oenotherae, the

21

monotype species of Discohainesia (Rossman et al. 2004). Thus, these two genus names are

taxonomically congruent. The type species of the genus Sclerotiopsis, S. australasica, was

considered a synonym of P. concavum by Palm (1991), thus this genus is also a synonym of

Pilidium. About twenty species of Pilidium and Sclerotiopsis each have been described, but

Pilidium is the most widely used generic name. Several plant pathogenic species of Pilidium

have been described in the recent literature (Rossman et al. 2004) .

Use Ploioderma 1967 rather than Cryocaligula 1986

The monotypic genus Cryocaligula based on the type species C. hedgcockii was described for

the asexual morph of Ploioderma hedgcockii, the type species of Ploiederma, thus these

genera names are synonyms. The name Cryocaligula has not been used since it was described

while the older Ploioderma includes 11 names and is well known, thus the use of Ploioderma

is recommended.

Use Pragmopora 1855 rather than Pragmopycnis 1975.

Although the type species of Pragmopora, P. amphibola, was initially considered to be a

doubtful lichen, later authors, most recently Groves (1967), concluded that a thallus was

lacking in this species. He accepted six more species in his monograph of this genus

including P. pithya. The type species of the monotypic genus Pragmopycnis, P. pithya, was

described as the asexual state of Pragmopora pithya, thus these genera are regarded as

taxonomically congruent. None of these species have been sequenced. Pragmopora is most

frequently cited and has priority, thus its use is recommended.

Conserve Pyrenopeziza 1870 over Cylindrosporium 1823

The genus Pyrenopeziza includes a number of important plant pathogenic species. Although

reported several times from Europe on members of the Apiaceae, the type species, P.

chailletii, has not been well-characterized. One important plant pathogen, P. brassicae, has

been linked to the asexual name Cylindrosporium concentricum, type of the genus

Cylindrosporium (Rawlinson et al. 1978, Cheah et al. 1980). Assuming that P. chailleti is

congeneric with P. brassicae, then Cylindrosporium provides an older generic name for these

species and these generic names would be considered taxonomically congruent. Both genera

22

include about 400 names although most remain obscure. The name Pyrenopeziza is more

commonly used than Cylindrosporium. Given the many plant pathogenic species in the genus

Pyrenopeziza, it seems expedient to conserve the name Pyrenopeziza over Cylindrosporium.

Conserve Rhabdocline 1922 over Meria 1896, Hartigiella 1900, and Rhabdogloeum 1922.

Rhabdocline and its asexual genus Rhabdogloeum were described in the same article based in

different type species (Sydow & Petrak 1922). The type species of Rhabdogloeum, R.

pseudotsugae, is connected to Rhabdocline weirii according to Parker & Reid (1969). The

genus Rhabdocline is clearly defined to include both the type species of Rhabdocline, R.

pseudotsugae and R. weirii by Stone & Gernandt (2005), thus the genera Rhabdocline and

Rhabdogloeum appear to be taxonomically congruent. Rhabdocline includes nine names and

is slightly more commonly used than Meria, which includes only two names. Of the two

species of Meria, M. parkeri already has a Rhabdocline name; M. laricis Vuill. will need to

be placed in Rhabdocline. Two older asexual genera are also considered synonymys of

Rhabdocline, namely Hartigiella and Meria. Gernandt et al. (1997) showed the respective

type species of Meria and Rhabdocline to be congeneric, thus Meria is taxonomically

congruent with Rhabdocline. The type species of Allescheria laricis R. Hartig 1899 is the

basionym of the monotype species of Hartigiella, H. laricis (R. Hartig) Dietel & P. Syd.

1900, a synonym of Meria laricis (Vuillimen 1905), thus Hartigiella is also taxonomically

congruent with Rhabdocline. Note that two additional Meria species belonging in the

Clavicipitaceae were recombined in Drechmeria by Gams & Jannson (1985). Given its more

common use, conserving the name Rhabdocline for this genus seems expedient.

Protect Rhizothyrium 1915 over Rhizocalyx 1928.

The type species of Rhizothyrium, R. abietis, was shown to be the asexual morph of

Rhizocalyx abietis, type species of Rhizocalyx by Smerlis (1967), thus Rhizothyrium and

Rhizocalyx are synonyms. Based on Petrak’s (1928) hypothesis about the relationships of

these taxa, Smerlis (1967) grew both states in culture and provided convincing descriptions

23

and illustrations. While Rhizocalyx remains monotypic, a second species of Rhizothyrium, R.

parasiticum, was described by Butin (1986). No molecular data exist for either genus.

Although both genera are relatively obscure, Rhizothyrium has been used s more often than

Rhizocalyx, thus it seems most useful to protect the earlier name Rhizothyrium for this genus.

Use Rhytisma 1818 rather than Melasmia 1846

The type species of Rhytisma, R. acerinum, is the sexual morph of the type species of

Melasmia, M. acerinum (Cannon & Minter, 1984), therefore the genera are synonyms.

Melasmia is a morphologically simple, putatively spermatial anamorph. The genus Rhytisma

has been widely used for species causing various tar spot diseases on living leaves.We

recommended that the older, relatively well characterised Rhytisma be used.

Use Scleropezicula 1999 rather than Cryptosympodula 1999

These monotypic genera were described for the sexual and asexual states of the same species,

therefore, the genera are synonyms. Neither name has been widely used but the sexual state

has been more frequently reported and is already in Scleropezicula therefore we recommend

the use of the sexual morph name Scleropezicula.

Use Seaverinia 1945 rather than Verrucobotrys 1973

The type species of Verrucobotrys, V. geranii, was established for the asexual morph of the

type species of Seaverinia, S. geranii, thus these genera are synonyms. Both genera are

monotypic. Given the equal citation of these names, the older Seaverinia should be used.

Use Septotinia 1961 rather than Septotis 1970

The type species of Septotis, S. podophyllina, was established for the asexual morph of the

type species of Septotinia, S. podophyllina, thus these genera are synonyms. Both genera are

monotypic. Given the equal citation of these names, the older Septotinia should be used.

Use Stamnaria 1870 rather than Titaeospora 1916

24

Stamnaria persoonii, type species of Stamnaria, is a relatively common fungus on stems and

leaves of Equisetum spp. in temperate regions (Farr & Rossman 2014). The asexual state of

Stamnaria persoonii is regarded as Titaeospora equiseti of which the type species of

Titaeospora, T. detospora, is a synonym (Arx 1970), thus Stamnaria and Titaeospora are

synonyms. Given the equal number of species and the equal use of names in these genera, the

older genus Stamnaria should be used.

Use Streptotinia 1945 rather than Streptobotrys 1973

Although Hennebert (1973) stated that the genus Streptobotrys was the asexual morph of

Streptotinia, the type species of Streptobotrys, S. streptothrix, does not have a known sexual

morph. The other two species of Streptobotrys are listed with their corresponding sexual

morphs including Streptotinia arisaematis, the type species of Streptotinia. Thus these two

genera are taxonomically congruent. Given that the number of species in each genus is small

and both generic names are cited about equally, the older name Streptinia should be used.

Use Strossmayeria 1881 rather than Pseudospiropes 1971

The sexual morph of P. nodosus, the type species of Pseudospiropes is regarded as

Strossmayeria atriseda (Saut.) Iturr. by Iturriaga & Korf (1990) who also regard S. atriseda as

congeneric with the type species of Strossmayeria, S. basitricha, thus Strossmayeria and

Pseudopsiropes are taxonomically congruent. They suggest that the asexual states of species

of Strossmayeria are always referrable to Pseudospiropes, but note that other phylogenetically

distant, morphologically similar asexual species have been described in Pseudospiropes. We

recommend use of the older, well characterised name Strossmayeria.

Use Symphyosirinia 1956 rather than Symphyosirella 2009

Although the type species of Symphyosirinia based on S. galii and the type species of

Symphyosirella, S. parasitica are not synonyms, they are considered to be congeneric (Gams

et al 2009), thus these genera are taxonomically congruent. Although neither genus is widely

used, Symphosirinia is marginally in wider use and has priority, thus this genus is

recommended for use. Priority at the species level will require recombination of

Symphyosirella parasitica and S. rosea into Symphyosirinia, following the discussion in

25

Gams et al. (2009) that these two species are congeneric with the asexual states of

Symphyosirinia.

Use Tympanis 1790 rather than Sirodothis 1909 or Pleurophomella 1914

The type species of Tympanis, T. saligna, is considered the sexual morph of Sirodothis

saligna while the type species of Sirodothis, S. populi is a synonym of S. populnea, the

asexual morph of Tympanis spermatiospora (Sutton & Funk 1975), therefore these genera are

taxonomically congruent. The type species of Pleurophomella, P. eumorpha, has been linked

to “one of the three species.” f Tympanis on Pinus (Groves 1949), possibly T. confusa, and

thus is also taxonomically congruent with Tympanis. The genus Tympanis has many more

species than Sirodothis and Pleurophomella and is widely used. We recommend use of the

well known genus Tympanis.

Use Unguiculariopsis 1909 rather than Deltosperma 1988

When Zhuang (1988) monographed the genus Unguiculariopsis, she established the genus

Deltosperma based on D. infundibuliformis for the asexual state of U. infundibuliformis. The

type species of Unguiculariopsis, U. ilicincola, was included in that genus by Zhuang (1988),

thus Unguiculariopsis and Deltosperma are taxonomically congruent. Given that there are

many more species of Unguiculariopsis than Deltosperma and that Unguiculariopsis is more

frequently cited, the older name Unguiculariopsis should be used.

Protect Valdensia 1923 over Valdensinia 1953 and Asterobolus 1972

Valdensinia based on V. heterodoxa was established for the sexual morph of Valdensia

heterodoxa, now type of Valdensia (Peyronel 1923, 1953), thus Valdensia and Valdensinia

are synonyms. This species has an asexual morph that produces large staurosporous conidia

quite unlike the discoid sexual morph. Nevertheless these forms represent the same species in

26

the Sclerotiniaceae (Holst-Jensen et al. 1997) and cause a leaf-spot disease of ericaceous

plants as well as others hosts. Although both generic names have been used, more reports

have been made using the asexual genus, thus Valdensia is proposed for protection.

According to Redhead & Perrin (1972) their genus Asterobolous based on A. gaultheriae is a

synonym of Valdensia while Gloeosporium myrtillii, the type species of Saliastrum (Kujala

1946), is not a synonym of Valdensia heterodoxa.

Conserve Xylogone 1969 over Scytalidium 1957

The type species of Xylogone, X. sphaerosperma, and the type species of Scytalidium, S.

lignicola, were shown to be congeneric in the phylogenetic analyses by Kang et al. (2010)

that included a second species of Xylogone, X. ganodermophthora, and a second species of

Scytalidium. Thus, Xylogone and Scytalidium are taxonomically congruent. The medically

important and plant pathogenic species known as Scytalidium dimidiatum is now placed in

Neoscytalidium as N. hyalinum (Phillips et al. 2013) in the Botryosphaeriaceae (Crous et al.

2006). The remaining species of Scytalidium are of unknown affinities many of which were

isolated from soil and wood but also animals including humans; two species are thermophilic

(Straastma & Samson 1993). Given the phylogenetic diversity of the species currently placed

in Scytalidium, we suggest that Xylogone be conserved for the well-circumscribed genus that

includes the type species of both genera.
